Yamamoto Glycerin Filled Pressure Gauge 

 

Features

The Yamamoto Glycerin Filled Pressure Gauge is specially designed for applications subjected to heavy vibration or continuous pressure fluctuations. The gauge is filled with glycerin oil, which effectively dampens pointer vibration, minimizes wear on the internal movement mechanism, and significantly extends the service life of the instrument.

Thanks to its excellent vibration-resistant performance, this type of pressure gauge is widely used in air compressor systems, industrial pumps, hydraulic systems, oil & gas facilities, chemical plants, and production lines with high levels of vibration.
